avast! is a package of applications that aim to protect your computer from a possible virus infection or other malware threat. If you use it correctly, and in combination with other programs such as data backup utilities, it will significantly reduce the risk of your computer being attacked or infected by a virus, and thus the risk of losing important or private data.

The Avast! Internet Security application comes with an antispam filter and built-in firewall. Once installed, avast! runs silently in the background to protect your computer against all known forms of malware. You don’t need to do anything else - just install and forget!

Active internet users need greater protection for themselves as they shop and bank on-line. To secure against threats from infected web sites and the growing risk of identity theft, avast Internet security provides you with continuous protection from its layers of antivirus, anti-spyware, anti-rootkit protection, firewall and antispam.

Real-time shieldsThe real-time shields are the most important part of the program, as they are working continuously to prevent your computer from becoming infected. They monitor all your computer’s activity, checking all programs and files in real-time - i.e. at the moment a program is started or whenever a file is opened or closed.

Virus ChestThe virus chest can be thought of as a folder on your hard disk with special properties, that make it a safe, isolated place for storing potentially harmful files. You can work with the files in the virus chest, with some security restrictions.

Spam delivered to your mailbox can result in your mailbox quickly becoming full, as a result which, legitimate emails may not be received. It can also unnecessarily increase the load on the email server, internet connection, local networks etc.

Firewallavast! Internet Security includes a fully integrated firewall which can be controlled directly from the avast! user interface.

The firewall monitors all communication between your computer and the outside world and blocks unauthorized communication based on a number of “allow” and “deny” rules. In this way, the firewall can prevent sensitive data from leaving your computer and can also block attempted intrusions by external hackers

Command-line scannerThe ashCmd program uses the same avast! scanning engine to detect potential malware infections so the results are exactly the same as running a scan via the normal program interface. The avast! command-line scanner, ashCmd.exe, is normally installed in the directory C:Program FilesAlwil Softwareavast5.

A scan is run from the command prompt using various switches and parameters. To see a description of the parameters, locate the ashCmd file and double click on it. This will open a new window in which the various parameters are displayed.

Based on the award-winning avast! antivirus engine, avast! antivirus contains all of the features you would expect in a modern antivirus program. It incorporates anti-spyware technology certified by West Coast Labs’ Checkmark process, as well as anti-rootkit and strong self-protection capabilities, but now provides even faster scanning with improved detection ability. It contains several real-time “Shields” which continuously monitor your email and internet connections and check the files on your computer whenever they are opened or closed.

- Continuous protection against viruses and spyware- Ensures all mails sent and received are clean- Keeps you protected from “chat” infections- Stops attacks from hijacked websites- Lets you safely browse suspicious websites or run unknown applications- Allows safe and uninterrupted gaming

Here are some key features of “Avast! Pro Antivirus”:- Core and detection- Antivirus and anti-spyware engine- State of the art scanning engine provides reliable protection against viruses, spyware and other forms of malicious software.

- Real time anti-rootkit protection- Unique “on access” technology checks all kernel-mode drivers that the operating system is loading for signs of rootkit behavior. This enables even unknown rootkits to be detected and stopped before they can do any damage.- avast! Sandbox- Enables potentially exploitable programs (such as web browsers) and/or suspicious executables to be run in a safe, virtual environment. The avast! Sandbox is unique as it runs on both 32 and 64bit platforms.

- avast! Community IQ- Most samples we process come from sensors deployed throughout the avast! community in the Behavior shield and anti-rootkit modules. This is a unique source of data made possible only thanks to our huge user base. Most of the collected samples are analysed by a number of automated processes and only a small fraction of the samples need to be processed manually by our virus analysts.

- Code emulator- When a suspicious executable is encountered (during both on-demand and on-access scanning), avast! is able to emulate the program-s code in an isolated environment. The code emulator is used for two purposes. First, it is used for generic unpacking. Secondly, it is used in the heuristics engine. Technically, this is done using dynamic translation, a method much faster than traditional emulation techniques.

- Heuristics engine- Starting with version 5.0, avast! features a new heuristics engine designed to proactively detect malware undetectable with normal definitions. The heuristics engine is able to cover both binary (executable) and script malware.

- Potentially unwanted programs detection- New in version 5.0, avast! now detects potentially unwanted programs, such as remote admin tools and commercial key loggers. Custom rules can be set for dealing with these types of programs.

- Scanning- Boot-time scanner- Allows you to scan your computer for infections before the operating system has started and before a virus can be activated (32-bit operating systems only).

- Command-line scanner- Enables you to run a scan directly from the command line.

- Wake-up for scan- Microsoft Windows is woken from sleep or hibernation mode, performs a scheduled scan, then returns back to sleep mode.

- Scheduled scanning- Allows users to define the scan time and files to be scanned.

- avast! Intelligent Scanner- Can reduce the number of required file scans by up to 80% through a white list of proven safe applications. Files identified as safe are not rescanned unless they change.

- Shields- Behavior Shield- Monitors activity on your computer using a number of sensors (file system, registry and network based) and reports/blocks any suspicious behavior.

- Mail Shield- Scans all incoming/outgoing e-mails for malware. For MS Outlook, a special plug-in is used. Other email clients are protected by a generic POP3/IMAP4/SMTP proxy. New inversion 5, the proxy also supports scanning of SSL communication ( gmail.com, sympatico.ca, -.)

- Network Shield- Provides protection against network-based viruses. The module has two main components: a URL blocker, designed to block malicious URLs (as defined by the Virus Lab), and a lightweight intrusion-detection system.

- Fast application of updates- New format for the virus definition file speeds up application of updates into avast! 5.0 and reduces demand on CPU/memory, resulting in uninterrupted computer use.- New format for the virus definition file means faster updates and reduces demand on CPU/memory, resulting in uninterrupted computer use.

What’s New in This Release:- New Script Shield - now scanning deeper and supporting more host processes- Web Shield now scanning all processes by default- Stability improvements in aswSP.sys- Better tracking of file sources- WebRep now working in new versions of Firefox- Under-the-hood improvements in the Behavior Shield and Sandbox modules- Solved a compatibility problem with certain Steam-based games- Minor improvements in the product UI- Various other security and stability related fixes
